Any authenticated database role can run them, and neither checks privileges. A low-privileged user can call gp_expand_lock_catalog() inside an open transaction to block all catalog changes across the cluster for every user, superusers included, until that transaction ends, which in practice requires a superuser to terminate the session. Blocked changes include DDL, temporary table creation, GRANT and CREATE ROLE. The same user can call gp_expand_bump_version() repeatedly. Each call disconnects sessions that hold temporary tables, with a FATAL error on their next catalog change, and makes every other session rebuild its segment connections.","publishedAt":"2026-10-21T13:53:54.574Z","updatedAt":"2026-10-30T18:02:53.219Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"EDB"},"assigner":"EDB","products":["EnterpriseDB WarehousePG"],"affected":[{"vendor":"EnterpriseDB","product":"WarehousePG","defaultStatus":"unaffected","versions":[{"version":"6.27.1","status":"affected","lessThan":"6.27.7","versionType":"semver"},{"version":"7.2.1","status":"affected","lessThan":"7.6.1","versionType":"semver"}],"repo":"https://github.com/warehouse-pg/warehouse-pg"}],"references":["https://www.enterprisedb.com/docs/security/advisories/cve2026104948/"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-30T18:20:07.061Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/104xxx/CVE-2026-104948.json","commit":"55f8edbf9d47efa62275e8ca91bb2e15e821b559","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-104948","state":"PUBLISHED","datePublished":"2026-10-21T13:53:54.574Z","dateUpdated":"2026-10-30T18:02:53.219Z","assignerShortName":"EDB","assignerOrgId":"20be33e2-bf35-4d13-8fad-18bd2f3e3659","dateReserved":"2026-10-02T17:51:49.010Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"WarehousePG (WHPG) 6.27.1 through 6.27.6 and 7.2.1 through 7.6.0 are affected by a missing authorization vulnerability (CWE-862) in the built-in cluster expansion functions gp_expand_lock_catalog() and gp_expand_bump_version().
